Mr. Gasket Steel Shim Cylinder Head Gaskets are for high performance street machines, drag racing and oval track racing. With today's extreme compression ratios you need stronger more durable gaskets. Mr. Gasket steel shim gaskets are made from .020 inch steel shim stock which is thinner than most composite gaskets increasing engine compression. Stress formed embossments will seal the extreme cylinder pressure.

Features:

  • Manufactured from .020" steel shim stock.
  • Thinner than composition head gaskets - increases engine compression.
  • Stress formed embossments seal extreme cylinder pressures.
  • For high performance street, drag race and oval track use.
